Batman: Arkham City is the marquee title in this month’s PlayStation Plus Instant Game Collection update.

Rocksteady’s acclaimed DC adaptation is joined by third-person shooter/slidefest Vanquish, both of which are available from today on the PlayStation 3, along with eerie puzzler Limbo.

The big Instant Game Collection title on the Vita is Mortal Kombat, available from December 19.

Thanks to Cross Buy, two games will be available for free on both the Vita and PlayStation 3 this month: shoot ‘em up Big Sky Infinity (December 12), and puzzle platformer Knytt Underground (December 21).

Crysis 2, Scott Pilgrim vs The World, Double Dragon Neon, Chronovolt, and Tales From Space: Mutant Blobs Attack are being removed from PlayStation Plus this month, so if you haven’t downloaded them already, now is the time to do so.

Bulletstorm, Resident Evil 5 Gold Edition, Motorstorm Apocalypse, Ratchet and Clank All 4 One, Cubixx HD, LittleBigPlanet 2, inFamous 2, and Hell Yeah: Wrath of the Dead Rabbit are still available for PlayStation 3 on the service, with Uncharted: Golden Abyss and Gravity Rush still available for the Vita.
